Slow Cooker Meatball Stroganoff Recipe with Frozen Meatballs and Pantry Staples

Five minutes of prep and the slow cooker does the rest. Dump in a bag of frozen homestyle meatballs, a packet of brown gravy mix, a packet of onion soup mix, and a can of cream of mushroom soup. Stir in the sour cream at the very end, off the heat, and the sauce turns silky enough to coat the back of a spoon and cling to every egg noodle.

This is my Wednesday night dinner. The kind of night where church runs late and nobody has eaten. I start it earlier in the day, and it’s ready when we walk back in the door. It’s also the dish I take to potlucks, because it holds on warm for a couple hours without turning to mush.

Ingredients

You can use homestyle, beef, or turkey meatballs—avoid Italian-style (with herbs like oregano or fennel) since the flavor competes with the creamy stroganoff sauce. Mushrooms are optional.

Step-By-Step Instructions

Start by adding the frozen meatballs to the slow cooker. Sprinkle on the packet of gravy mix, onion soup mix, minced garlic, Worcestershire sauce, and condensed cream of mushroom soup.

Pour in the beef broth and stir until everything is combined and no dry pockets of seasoning are left. Put the lid on and cook for six hours on low or three hours on high. Don’t lift the lid to check on it. Every peek adds fifteen or twenty minutes back to the cook time.

When the time is up, turn the cooker off and let it sit for five minutes before you add the sour cream. Stir it in gently, then fold in the cooked egg noodles and serve.

Don’t add the sour cream while the cooker is still hot and bubbling. It will break and turn grainy. Off, wait five minutes, then stir.

Troubleshooting

• Sauce too thin: leave the slow cooker lid off and keep it turned on for fifteen to twenty minutes before you go to add the sour cream. Or, you can stir in a tablespoon of cornstarch mixed with two tablespoons of cold water and give it 10-15 minutes.
• Sauce too thick: thin it with a splash of warm beef broth, a couple tablespoons at a time, until it coats the noodles instead of gluing them together.
• Sauce broke and looks curdled: it still tastes fine. Stir hard and serve it over the noodles, the texture mostly disappears. Full-fat sour cream at room temperature breaks less than cold light sour cream.
• Noodles: stir them in right before serving, not ahead. If you’re feeding people at different times or taking this to a potluck, keep the noodles in a separate dish and let everybody spoon the stroganoff over their own. Noodles sitting in the sauce swell and go soft within about thirty minutes.

I love serving this dinner with some homemade buttermilk biscuits because they soak up every bit of that creamy stroganoff sauce.

Storage And Reheating Instructions

Keep any leftovers in an airtight container and refrigerate for up to four days. To reheat, add to a microwave-safe dish and add a splash of beef broth. Microwave until the beef reaches a temperature of 165 degrees Fahrenheit with a digital thermometer. Or, add to the stovetop on medium heat and bring it to the same temperature.
